           Summary: Why does WebKit run into JavaScript1.7 blocks without
                    supporting any feature of JavaScript 1.7
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
               URL: https://developer.mozilla.org/en/New_in_JavaScript_1.7
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P3
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: georg at bioshop.de


Why does WebKit run into JavaScript1.7 blocks without supporting any feature of
JavaScript 1.7. From the results of my tests, I confirm Safari 3.2 supporting
JavaScript 1.6, but testing those language features that make the difference
between 1.6 and 1.7 WebKit 528+ fails in each test case. It neither supports
block scope variables using the new keyword let nor does it support generators
using the new keyword yield nor does it support de structuring assignments.

Without implementing these language features, it should not run into
javascripts with language="javascript1.7" or
type="application/javascript;version=1.7" because those scripts usually make
use of exactly those language features not yet implemented in WebKit.
